Is ULTIM8 deck safe to use in hot temperatures of 40°C (104°F)+?

Is ULTIM8 deck safe to use in hot temperatures of 40°C (104°F)+?

Yes! ULTIM8 Bamboo Composite Decking is designed and tested to safely span 450mm (18.0″) centre to centre, in temperatures over 40°C (104°F)*.

Not all composite decking products are the same. Whilst some may appear similar in look and feel, they all have unique characteristics and differ in structural strength and quality. A little known fact is that some composites may lose strength in higher temperatures, with some losing 40% of their structural strength in temperatures of 40°C (104°F) or more. This may lead to deck failure under certain circumstances where the temperature reaches over 40°C (104°F).

Many composite decks may actually meet some local industry standards, which are self-regulated standards set by the industry. However, it is the Building Codes for flooring of the relevant country that are actually the laws that you will need to abide by at all times. For example, the Building Codes of Australia require that all flooring (decking included) must maintain its advertised or stated span under all temperature conditions for the area it is being installed. This is very important in areas where temperatures can reach 40°C (104°F) or more during summer when your deck will most likely be in regular use.

It is the responsibility of the supplier, the buyer, and the end user to ensure that decking sold meets the relevant Building Codes of the Country they are in. ULTIM8 Bamboo Composite Decking was designed, built and tested with your safety as our number one concern. Designed for the hot and harsh Australian climate, where temperatures regularly exceed 40°C (104°F), ULTIM8 Deck is more than capable of handling these conditions and retaining its strength and integrity, well above the minimum requirements. In countries like Australia where there are no national standards for composite decking, it is the regulatory and legal requirements of the BCA (Building Code of Australia) that are the sole guide to whether your deck meets its safety requirements.

ULTIM8 Deck meets all relevant standards, as well as the requirements of the Building Code of Australia for flooring.

Relax! You are safe when you choose the ULTIM8 Deck!

*MCX recommend a shorter span of 400mm (16.0″) as a safety precaution for installations where temperatures regularly reach 50°C (122°F). Please contact MCX at for further information before installing.
